Data integration advances reproductive phenology research across temporal, spatial and taxonomic scales

Ecography, EarlyView.
Climate change is altering plant reproductive phenology; however, a scarcity of long‐term, systematic monitoring hinders our ability to quantify and predict these responses in many parts of the world. We addressed this gap by demonstrating how data integration can be used to produce a synthesised record of reproductive phenology observations (flowering

A dynamic and stochastic analysis of fertilizer use in swidden agriculture [PDF]

The number of times a crop can be harvested on a cleared parcel of forest land (CPFL) before this land must be fallowed is dependent on the decision to use or not to use fertilizers to enhance soil fertility.

Successful Implementation of Environmental Policy and Governance: Understanding and Modeling Micro Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Successful implementation of environmental policy and governance highly depends on the capacity to know about, build new and utilize existing governance structures. However, the theoretical tools and available methods to assess the complexity of emerging or existing structures are rather limited.

Soil fertility impact on recruitment and diversity of the soil microbiome in sub-humid tropical pastures in Northeastern Brazil

Scientific Reports
Soil fertility is key point to pastures systems and drives the microbial communities and their functionality. Therefore, an understanding of the interaction between soil fertility and microbial communities can increase our ability to manage pasturelands ...

Management & sustainability of stockless organic arable and horticultural systems [PDF]

, 2008
The essential difference between stockless and stocked systems is that the fertility building clover ley and other “forage crops” are not processed through an animal but instead are grown as green manures which are returned directly to the soil by ...

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

European Policy Analysis, EarlyView.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
